IMPROVEMENT IN PORTFOLIO-STANDS.

Specification forming part of Letters Patent No. 167,584, datedSeptember 7, 1875; application filed July 30, 1875.

I a transverse vertical section.

Similar letters indicate corresponding parts.

This invention consists in the combination of one or two hingedspring-flaps with a stand composed of two side pieces, a verticalabutment, and a horizontal supporting-platform, so that by the combinedaction of the stand and the spring-flap a portfolio, or single sheets ofengravings or of music, or of any other nature, when placed between saidflap and the sition, and each portfolio or sheet can be convenientlyreached and taken from the stand. \Nith the stand-and the main flap iscombined a secondary spring-flap hinged to the main flap for the purposeof more eli'ectually retaining portfolios or single sheets in therequired position on the stand.

In the drawing, the letter A designates my stand, which is composed ofside pieces a, a central vertical abutment, b, and a horizontalplatform, 0. These parts are united by screws, so that the whole can bereadily taken apart for the purpose of packing it up in comparativelysmall space, and that the parts can be easily connected for use. To theplatform 0 are connected two flaps, B B, the connection being effectedby hinges d d. Said flaps extend beneath the platform, and their lowerends are subjected to the action of springs a, so that the upper partsof said flaps are forced inward against the vertical abutment b. Thesprings 6 can be made and applied in any desirable manner, but I preferto use a single spring, which extends through a slotted bracket, f, asshown in Fig. 2, and the ends of which act on the two flaps B B. Byforcing back the upper end of one of these flaps one or more portfoliosor single sheets of paper can be placed upon the platform 0, and byallowing the flap to close up said portfolios or sheets are retained inan upright position, and when either of them is required for use orinspection it can be easily selected and taken off from the standwithout disturbing the position of the remaining portfolios or sheets.With either or both of the main flaps B B is combined a secondary flap,O, which is hinged at its upper edge to its main flap, and which issubjected to the action of a spring, g. By the action of this secondaryspring-flap additional steadiness is imparted to the portfolios orsheets placed on the platform a, and my stand is rendered available forportfolios or sheets of various different sizes. vertical abutment, arefirmly retained in po- My stand is intended particularly for music, butit can be used for holding engravings or other sheets of paper, eithersingly or in portfolios. v

What I claim as new, and desire to secure by Letters Patent, is

1. The combination, with a folio-stand having a platform, 0, a'verticalabutment, b, and supporting side pieces a, of aflap hinged upon theplatform, and having its lower end extending below the platform, whereit is subjected to the action of a spring for closing the flap,substantially as described.

2. The combination of the bracket f and spring 0 with the flaps B B,abutment b, and platform 0, substantially as described.

3. A secondary flap hinged upon the hinged spring side flaps, incombination with the' abutment b and platform 0.

In testimony that I claim the foregoing I have hereunto set my hand andseal this 29th day of July, 1875.
